Pagefile and SSD

[SuperFlower]

Just discovered this after hours of searching the internet. Basically if you let windows automatically manage pagefile, even if you don't max out your ram memory, your ssd will constantly write while gaming. 

Installed my brand new 970 evo plus 1tb on a fresh windows 11 install, played some games, today I've played watch dogs legion and HWinfo says it writed 10gb in 4 hours of gameplay. This happened without memory leaks or antivirus installed.

Those who do not believe, I challenge them to see for themselves, run Hwinfo in background and play some demanding games, you will see that it will write a lot on your ssd without you knowing it. Verify the tbw before and after playing the game.

Do you want your ssd to last 20-25 years? Or is there an actual point behind setting up your PF/Swap manually? Pagefile/Swap is a crucial part of any modern operating system, disabling it or manually setting it up is pointless. I have a 840 Evo 120G that I got in 2013, I written over few terabytes on it and it still shows %78 health.

 

You dont need to change your page file settings AT ALL. If you ran out of ram page file is used, if you run out of vram, ram is used and thus page file will be used.

Please read again, even if you dont run out of memory, pagefile will still write stuff on your ssd while you play games.

Yeah because it's doing exactly what it's supposed to do. It puts long term not currently active stuff from the ram onto the disk so that ram is available when need be. It is smart to know when to do that and when not to to avoid overdoing writing.

 

So I don't see a problem here. It's working as intended. What is the problem here?

Computers using the resources you give them   Every now and then threads of people being concerned about the amount of RAM Windows is "using" or worried their CPU/GPU being at 100% is damaging it. Especially when it comes to memory people for some reason like to see massive unused amounts. I get that it's satisfying to see 32 GB of RAM free, but at the same time the OS or something else would be a fool not to take advantage of it if it's there.

I see this mentioned way to often.

Your 970 EVO Plus 1TB has a endurance rating of 600TBW or 5 Years, that is what Samsung guarantees it for.

So lets break this down over the 5 Year Guarantee with a 24 hour constant operation.

 

You would need to write

• 120TB a Year
• 10TB a Month
• 336.7GB a Day
• 14GB a Hour

You say your Page File wrote 10GB of Data over 4 Hours, or 2.5GB a hour, which still leaves 11.5GB  a hour of available write endurance, it's  also unlikely that your Page File actually maintains a constant 2.5GB a hour.

 

Now lets say you only use your system for 6 hours a day, your Page File is still consuming 2.5 GB a hour, and you average 10GB a hour of Data Writes. You would consume around 26.8 TB a Year. It would take around 22 years to fill it's endurance rating, far surpassing it's 5 year guarantee.

 

Now lets take away your Page File with the same 6 hours above leaving us at just 10GB a hour. You would consume around 21.4TB a Year. It would take around 28 years to fill it's endurance rating.

 

Now if we take into account your Page File is possibly only consuming 2.5GB a hour at a quarter of the time and we split the difference of 6 years, Your looking more at a 1.5 year difference, or a 26.5 year possible lifespan.

 

Now the chances that the drive won't die for another reason unrelated to Data Writes and that you will still have this drive in 20+ years is pretty small.

 

In other words, don't worry about it.

I’ve never seen the math on this thank you for putting me at ease.
